I am trying to utilize a script to enable my monitors on a Windows 8.1 system
after "Turn off the display" power saving and having no luck at all. The script is fired off by a motion sensor in the room, so that when a user's presence is detected it will automatically light up the display. The only way I've found so far
to wake the monitors is to physically move the mouse or press a key.
I have the Windows power settings set to "Turn off the display" after
1 minute (for testing) and "Put the computer to sleep" set to "Never". When the system goes into powersave for the monitors, the
monitors sleep and go dark. The control panel on the base on the monitors
also go dark in response. When I issue most of the commands I've tried below, the control panel on the monitor lights up but the monitors themselves never turn back on. It's like the computer is exiting powersave but not waking up the screen until something
physically moves.
Here is what I've tried:
- nircmd monitor on (hangs)
- nircmd monitor async_on (doesn't hang but doesn't turn the monitor on)
- AutoIt script to move the mouse (move 100x by 100y)
- Wake on LAN from remote system
- Powershell script to simulate local keyboard input or mouse movement
Nothing seems to work outside of physically touching a button or moving a mouse. Has anyone gotten something like this to work?
Note:
I asked this question previously and wasn't able to respond in time to prevent a non-working suggestion marked as an answer. I'm re-issuing this question in hopes of an answer that will work.
